We've all heard about the different types of hormones in our bodies. We talk about some of them all the time, and even doctors talk about them. But have you heard of a hormone called Adiponectin ? Maybe you haven't. But it plays a very important role in our bodies, especially in things like our weight and blood sugar levels. So, today, let's talk about Adiponectin in a simple, straightforward way.
What is Adiponectin? It's very simple!
Simply put, adiponectin is a protein hormone that is mainly produced by fat cells, or adipose tissue, in our bodies. It is also called an adipokine , because it is produced in association with fat. However, it is not only produced by fat cells, but also in some other parts of our bodies.
This guy called Adiponectin was discovered in the 1990s. That means scientists are still learning a lot about it. Perhaps there are other things this hormone does that we don't know about yet. As far as we've found, it mainly helps increase our body's sensitivity to insulin and reduce inflammation in the body .
What are the benefits of Adiponectin for our body?
This friend called Adiponectin is involved in many important processes in our body. Let's look at two of the most important ones.
1. How to sensitize our body to insulin
Do you know what insulin is? Simply put, insulin is like a key that opens the door to let sugar (glucose) into our body's cells. Being sensitive to insulin means that this key can open the door properly. Then the body can easily use sugar and keep blood sugar levels at the right level.
So, this is how Adiponectin helps:
- Your skeletal muscle and liver help your body respond to insulin properly.
- Increases the release of insulin from the pancreas.
- It stops the unnecessary storage of sugar called glycogen in the liver.
- It helps break down fatty acids and create energy.
Think about it, your body's cells are like houses. Insulin is the one that carries food called sugar to those houses. Adiponectin helps bring this food in through the door. Then the house gets food, right?
2. How to reduce inflammation in the body
Inflammation is when our immune system sends out cells to fight something like bacteria or to heal a wound. Sometimes this is necessary. But chronic inflammation , which means having a constant burning sensation inside the body, is not good for the body. Imagine that your body is constantly on fire... That's what chronic inflammation is.
Adiponectin helps reduce inflammation in the following areas:
- Macrophages (a type of white blood cell that engulfs and kills things like bacteria and viruses)
- Endothelial tissue (these are cells that form a thin membrane that lines the inside of the heart and blood vessels)
- Muscle cells
- Epithelial cells (these are the cells that cover all surfaces inside and outside the body)
By reducing inflammation in this way, Adiponectin protects these organs:
- Vascular system
- Heart
- Lungs
- Colon
Where is Adiponectin produced in our body?
Adiponectin is primarily made and released by cells called adipocytes, which store energy in our white adipose tissue . White adipose tissue is the main type of fat in our bodies. It is found in:
- Subcutaneous fat - that is, the layer of fat that we feel when we touch it.
- Visceral fat - This is the fat inside the belly that can be a little dangerous.
- Bone marrow (marrow fat)
Adiponectin can also be produced by other cell types:
- Skeletal muscle cells
- Heart muscle cells
- Endothelial cells
How are adiponectin levels controlled?
As I mentioned before, adiponectin is a relatively new discovery. So scientists are still researching it. So far, several hormones have been found to help regulate adiponectin levels.
Although the hormone insulin seems to be involved in this, not everyone agrees on exactly how it happens.
Insulin-like growth factor (IGF-1) and growth hormone (GH) control the release of adiponectin from fat tissue. Leptin (another hormone produced by fat cells) may also be involved.
How to check Adiponectin levels?
You can check your Adiponectin levels with a blood test .
Doctors sometimes order an adiponectin blood test to help diagnose conditions like type 2 diabetes and metabolic syndrome . However, there are other tests that are more commonly used to diagnose these conditions.
What should normal adiponectin levels be like?
Normal levels of adiponectin vary depending on your gender and Body Mass Index (BMI) , which is your weight for your height.
Typical Adiponectin ranges for men are as follows:
- If BMI is less than 25: 5 to 37 micrograms/milliliter (5 to 37 ug/mL)
- If BMI is between 25 and 30: 5 to 28 ug/mL
- If BMI is over 30: 2 to 20 ug/mL
Typical Adiponectin ranges for women are as follows:
- If BMI is less than 25: 5 to 37 ug/mL
- If BMI is between 25 and 30: 4 to 20 ug/mL
- If BMI is over 30: 4 to 22 ug/mL
The important thing is that these numbers can vary slightly from person to person and from lab to lab. So, check the normal range on your lab report. If you have any questions about your results, be sure to ask your doctor or nurse.
What diseases can develop when adiponectin levels are abnormal?
There are several health conditions that have been associated with abnormal levels of adiponectin. These include:
- Obesity and underweight
- Insulin resistance
- Atherosclerosis
- Lipodystrophy
Many of these conditions are associated with low levels of adiponectin .
Adiponectin and Obesity
Obese people have low levels of adiponectin. On the other hand, people who are extremely thin, whether due to conditions like anorexia nervosa or malnutrition, have high levels of adiponectin.
Simply put, as a person's body fat increases, their adiponectin levels decrease. Similarly, as body fat decreases, their adiponectin levels increase. When an obese person loses weight, their adiponectin levels increase.
Adiponectin and Insulin Resistance
Because adiponectin helps increase insulin sensitivity, people with insulin resistance typically have low levels of adiponectin. Insulin resistance is when your body's cells don't respond properly to insulin, causing your body to release too much insulin (hyperinsulinemia).
Insulin resistance can lead to prediabetes , type 2 diabetes , and gestational diabetes . It is often associated with obesity. However, people who are not obese can also develop insulin resistance. Surprisingly, people who are insulin resistant without being obese also have low levels of adiponectin. This suggests that there is a genetic factor involved in insulin resistance and adiponectin.
Adiponectin and Atherosclerosis
Atherosclerosis is a condition where plaque builds up on the inside of your arteries, blocking them. It's like rust building up inside a water pipe.
Adiponectin has anti-inflammatory properties, which protect the heart and blood vessels. So, when adiponectin levels are low, the risk of developing heart diseases like atherosclerosis and heart attacks may increase.
Adiponectin and Lipodystrophy
Lipodystrophy is a very rare disease that causes fat loss in some areas of the body and excess fat accumulation in others.
Lipodystrophy can be present from birth, or it can develop later in life. Adiponectin levels are low in congenital and HIV- associated lipodystrophy. This may be because adiponectin is involved in the way body fat is stored.
Is there a treatment for abnormal adiponectin levels?
In fact, there are natural treatments that can help improve adiponectin levels. These include regular exercise and healthy weight loss. However, you should always talk to your doctor before making any major changes to your diet or exercise routine.
Diabetes medications such as metformin and thiazolidinediones have been found to increase adiponectin levels.
Scientists are currently researching drugs that work in a similar way to Adiponectin to treat chronic inflammatory conditions. That could be good news for us in the near future!
What is the difference between Adiponectin and Leptin?
Leptin and Adiponectin are both hormones made and released by your fat tissue, a type of adipokines. Leptin works by boosting metabolism and reducing appetite.
Like adiponectin, abnormal levels of leptin are also linked to obesity - but in a different way. Leptin levels increase as body fat increases. However, adiponectin levels decrease as body fat increases. Easy to remember, right?
Finally, the most important thing
You probably understand by now how important adiponectin is to our bodies. Since it's a relatively new discovery, scientists are still learning more about it.
If you have a metabolic condition like obesity or type 2 diabetes, you may have heard your doctor talk about adiponectin. If you ever have a question about a word your doctor says, don't be afraid to ask. They're here to help.
There's nothing to worry about when it comes to your adiponectin levels. Good health habits, a balanced diet, and an active lifestyle are often the best ways to keep these hormone levels in check. So, take care of your body, because health is the most important thing!
